3. Amount of refrigerant to be added
The amount of refrigerant that is shown in the table below is factory-charged to the outdoor units.
The amount necessary for extended pipe (field piping) is not included and must be added on site.
(1) Calculation formula
The amount of refrigerant to be added depends on the size and the length of field piping. (unit in m[ft])
Round up the calculation result to the nearest 0.1kg. (Example: 18.04kg to 18.1kg)
Round up the calculation result in increments of 4oz (0.1kg) or round it up to the nearest 1oz. (Example: 78.21oz to 79oz)
